Key Highlights
- Passkeys offer a safer and more convenient way to authenticate online accounts.
- They use cryptography to prove identity without storing private keys on websites, blocking phishing attempts.
- Passkeys can be used even on devices lacking biometric hardware, such as Windows PCs, with a simple PIN unlock.
- Password managers can sync passkeys across different platforms and operating systems for seamless access.
The Rise of Passkeys in Cybersecurity
Keeping your computer safe from cyberattacks is more critical than ever. The traditional password has long been the cornerstone of security, but it comes with real challenges. Many users reuse passwords across multiple sites, and even strong passwords can be compromised in data breaches.
What Are Passkeys?
Passkeys use cryptography to prove who you are when logging into an account. When you create a passkey, your device generates two keys—a public key that goes to the website, and a private key that stays on your device. During login, your device confirms your identity with the private key, which never leaves your device during sign-in. This process makes logins faster and safer by eliminating the need for long passwords.
Using Passkeys Without Biometric Hardware
A PC or Mac without a camera or fingerprint reader can still use passkeys. On Windows, you unlock them with your Windows Hello PIN. On Apple devices, you can use Touch ID, Face ID, or your passcode.
The key is having an updated operating system and browser that support passkeys. Password managers can act as central vaults for storing and syncing both traditional passwords and passkeys across different ecosystems.
Why You Still Need Passwords
While passkeys simplify authentication, they don’t eliminate the need for a secure password manager. Many websites still rely on passwords, and keeping strong, unique passwords for those accounts is essential. Passwords also serve as backup if you lose a device or can’t use your passkey.
Passkey Support by Platform
Passkeys are supported on Windows 10 and 11, macOS 13 Ventura or later, iOS/iPadOS 16 or later, and Android 9 and later. They sync securely through services like iCloud Keychain for Apple devices and Google Password Manager for Android and desktop users.
Setting Up Passkeys on Windows and Mac
To set up passkeys on a Windows PC:
- Open Settings → Accounts → Sign-in options. Set up Windows Hello PIN or biometrics.
- Visit a site that supports passkeys, choose Create a passkey, and confirm with your PIN or biometric.
To set up passkeys on Mac:
- Ensure iCloud Keychain is enabled. Go to Apple menu → System Settings → your name → iCloud, click Passwords and turn on Passwords & Keychain and enable syncing.
- Visit a site that supports passkeys, select Create a passkey, and confirm with Touch ID or your device passcode.
For more flexibility, password managers that support passkeys can store them for cross-platform access. This ensures you always have access to your credentials no matter what kind of device you use.
Conclusion
Embracing Passkeys in the Digital Age
Passkeys are a major upgrade over traditional passwords, but we’re not living in an all-passkey world just yet. Many sites still rely on passwords, and you’ll need backups if something happens to your device. Supplementing passkeys with a password manager is the best move right now; it lets you store, sync, and protect both passkeys and passwords under one roof.
The good news is that setting up passkeys takes just a few minutes, and once they’re enabled, logging in becomes faster and more secure.
